Description

Technical Field

[0001] This manual relates to the field of automotive steering wheel technology, specifically to a damper, damper kit, and steering wheel. Background Technology

[0002] Currently, the connection between the car steering wheel and the driver's side airbag is often achieved through a center clicker. The clicker and steering wheel frame are secured with steering wheel bolts. A damping mechanism and spring are mounted on the clicker; the damping's function is to control and buffer the vibrations generated by the airbag during driving. However, the damping design is currently quite limited; one damper can only be used with one type of steering wheel, requiring a new damper design for each newly developed airbag. The wide variety of damping types makes reuse difficult, limiting compatibility and hindering platform-based production. Furthermore, the design and development costs for damping mechanisms are high. Current damping mechanisms fall into two categories:

[0003] Scenario 1: Adjusting the stiffness of the damping mechanism to adjust the resonant frequency, but changing only the stiffness results in a very narrow frequency adjustment range.

[0004] Scenario 2: Adjusting the resonant frequency by adjusting the stiffness or weight of the damper, but the stiffness or weight of the damper is limited by factors such as materials and space.

[0005] The current technology is that different weights and shapes of DAB (airbag modules) require different damping mechanisms on the clicker. In order to adjust the new resonance frequency, a new damping structure needs to be developed, which results in higher costs. Summary of the Invention

[0006] In view of this, embodiments of this specification provide a damper, a damper kit, and a steering wheel. By opening a plurality of slots in the elastomer and providing adjusting parts on the clamping component that cooperate with the slots, the damping frequency of the elastomer can be changed from a first damping frequency to different second damping frequencies. By using clamping components with different numbers of adjusting parts, different frequencies of the damper can be achieved. One elastomer can be used with various clamping components with different numbers of adjusting parts, which is easy to produce and use on a platform and reduces the cost of developing a single damper.

[0007] This specification provides the following technical solution through its embodiments: a damper, comprising an elastic body, a clamping component, and a support component, wherein,

[0008] The elastic body is a sleeve component with a through hole, and the elastic body extends outward from both ends of the through hole to form a first limiting part and a second limiting part, respectively.

[0009] The support member includes a support portion and a connecting portion. The support portion is disposed at one end of the elastic body. The connecting portion passes through the through hole and engages with the clamping member disposed at the other end of the elastic body. The support portion abuts against the first limiting portion to restrict the clamping member from moving away from the second limiting portion.

[0010] The second limiting portion of the elastic body is provided with a plurality of grooves, which have a first damping frequency for adjusting the buffering effect. The clamping component includes an adjusting portion that cooperates with the grooves. The adjusting portion is embedded in the grooves, so that the damper has a second damping frequency that is different from the first damping frequency.

[0011] Preferably, the groove includes a plurality of first grooves, which are evenly distributed on the end face of the second limiting part. The second limiting part surrounds the first grooves, and the first grooves extend into the second limiting part along the direction of the through hole. The clamping member includes a first adjusting part that extends toward the second limiting part to form a first adjusting part that cooperates with the first groove.

[0012] Preferably, the groove includes a plurality of second grooves, the plurality of second grooves being arc-shaped and evenly distributed on the inner wall of the through hole, the second grooves extending along the direction of the through hole, and the clamping member including a second adjusting part extending toward the second limiting part to form a cooperating with the second groove.

[0013] Preferably, the groove includes a plurality of second grooves, the plurality of second grooves being arc-shaped pieces, the second grooves being evenly distributed on the inner wall of the through hole, the second grooves extending along the direction of the through hole, and the clamping member including a second adjusting part extending toward the second limiting part to form a cooperating with the second groove.

[0014] Preferably, the connecting portion has a notch, which cuts the cylindrical connecting portion into two sets of arc-shaped elastic sheets. The two sets of arc-shaped elastic sheets extend outward to form two sets of pressing portions, which press and fix the annular clamping component on the second limiting portion.

[0015] Preferably, the elastomer and the clamping component are made of materials with different stiffnesses, and the stiffness of the clamping component is greater than that of the elastomer, so that the second damping frequency is greater than the first damping frequency.

[0016] A damper kit includes an elastomer, a support member, and several clamping members. The elastomer has four evenly distributed slots, and each of the clamping members is provided with one or two sets of adjustment parts. One set of adjustment parts consists of two adjustment parts distributed diagonally. The elastomer, support member, and clamping members are any of the elastomer, support member, and clamping parts described above.

[0017] A steering wheel includes a mounting portion, a pan head screw, a spring, a support, and a damper as described in any one of the preceding claims. The damper is detachably mounted on the mounting portion. The support has a threaded groove that mates with the pan head screw. The screw portion of the pan head screw passes through the through hole and the spring and mates with the threaded groove. The spring is mounted between the support and the support member. The spring continuously pushes the support member away from the support until the clamping member abuts against the pan head portion of the pan head screw, thereby ensuring that the pan head portion of the pan head screw presses the clamping member onto the elastic body.

[0018] Preferably, the damper is detachably mounted on the mounting portion, comprising: the elastic body being mounted on the mounting portion, with the first limiting portion and the second limiting portion of the elastic body located on opposite sides of the mounting portion; the support member being mounted on the elastic body, with the support portion of the support member contacting the first limiting portion, and the connecting portion of the support member passing through a through hole; and the clamping member being mounted on the second limiting portion of the elastic body, with the adjusting portion on the clamping member corresponding to the groove on the elastic body, and the connecting portion of the support member engaging with the clamping member to fix the clamping member on the elastic body.

[0019] Preferably, the mounting portion includes a horn plate, the horn plate having a first through groove for the elastomer to pass through, the first limiting portion being located on a first side of the horn plate, and the second limiting portion being located on a second side of the horn plate.

[0020] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0021] By designing a new damper, several slots are opened on the elastomer, and an adjustment part that cooperates with the slots is set on the clamping component, so that the damping frequency of the elastomer can be changed from a first damping frequency to different second damping frequencies. By using clamping components with different numbers of adjustment parts, different frequencies of the damper can be achieved. One elastomer can be used for a variety of clamping components with different numbers of adjustment parts, which is easy to produce and use on a platform and reduces the cost of developing a single damper.

[0034] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0035] The following specific examples illustrate the implementation of this application.

[0037] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. The drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0039] Currently, there are two main types of existing damping mechanisms:

[0040] Scenario 1: Adjusting the stiffness of the damping mechanism to adjust the resonant frequency, but changing only the stiffness results in a very narrow frequency adjustment range.

[0041] Scenario 2: Adjusting the resonant frequency by adjusting the stiffness or weight of the damper, but the stiffness or weight of the damper is limited by factors such as materials and space.

[0042] The current technology is that different weights and shapes of DAB (airbag modules) require different damping mechanisms on the clicker. In order to adjust the new resonance frequency, a new damping structure needs to be developed, which results in higher costs.

[0043] The inventors conducted extensive and in-depth experiments and designed a damper, a damper kit, and a steering wheel.

[0044] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0045] like Figures 1-4 As shown, a damper includes an elastic body 1, a clamping component 2, and a support component 3, wherein,

[0046] The elastic body 1 is a sleeve component 101 with a through hole 102. The elastic body 1 extends outward from both ends of the through hole 102 in the extending direction to form a first limiting part 103 and a second limiting part 104.

[0047] The support member 3 includes a support portion 301 and a connecting portion 302. The support portion 301 is disposed at one end of the elastic body 1. The connecting portion 302 passes through the through hole 102 and engages with the clamping member 2 disposed at the other end of the elastic body 1. The support portion 301 abuts against the first limiting portion 103 to restrict the clamping member 2 from moving away from the second limiting portion 104.

[0048] The second limiting part 104 of the elastic body 1 is provided with a plurality of grooves, which have a first damping frequency for adjusting the buffering effect. The clamping member 2 includes an adjustment part that cooperates with the grooves. The adjustment part is embedded in the grooves, so that the damper has a second damping frequency that is different from the first damping frequency.

[0049] The two ends of the elastic body 1 extend outward to form a first limiting part 103 and a second limiting part 104, which facilitates the installation of the elastic body 1. By providing several grooves on the second limiting part 104 and adjusting parts that cooperate with the grooves on the clamping component 2, the damping frequency of the elastic body 1 can be changed from the first damping frequency to different second damping frequencies. By using clamping components 2 with different numbers of adjusting parts, different frequencies of the damper can be achieved. The first limiting part 103 of the elastic body 1 is supported by the support part 301 of the support member 3. The connecting part 302 of the support member 3 engages with the clamping component 2 to fix the clamping component 2 on the second limiting part 104 of the elastic body 1. One type of elastic body 1 can be used with various clamping components 2 with different numbers of adjusting parts, and can be used in steering wheels of different modules. It is easy to use in platform-based production and reduces the cost of developing single damping.

[0050] It should be noted that for the same elastomer 1, different frequency requirements can be achieved by changing the clamping component 2. The clamping component 2 can adopt a multi-cavity mold, which greatly saves mold cost and development cost.

[0051] It should also be noted that the first damping frequency is the initial damping frequency of the elastic body 1, and the second damping frequency is the damping frequency of the elastic body 1 after the adjustment part on the clamping component 2 is inserted into the groove.

[0052] like Figures 1-3 As shown, in some embodiments, the groove includes a plurality of first grooves 105, which are evenly distributed on the end face of the second limiting portion 104. The second limiting portion 104 surrounds the first grooves 105, and the first grooves 105 extend into the second limiting portion 104 along the direction of the through hole 102. The clamping member 2 includes a first adjusting portion 201 extending toward the second limiting portion 104 to form a mating part with the first grooves 105. A plurality of first grooves 105 are formed on the end face of the positioning part 104. The first grooves 105 extend into the interior of the second limiting part 104. When the first adjustment part 201 on the clamping member 2 is inserted into the first groove 105, the overall stiffness of the second limiting part 104 can be changed, thereby changing the damping frequency of the second limiting part 104. At the same time, the first grooves 105 are evenly distributed on the second limiting part 104, ensuring that after the first adjustment part 201 is inserted into the first groove 105, the second limiting part 104 can achieve a relatively uniform stiffness change.

[0053] It should be noted that the depth of the first groove 105 is not greater than the height of the second limiting part 104, so as to ensure that the first adjusting part 201 will not pass through the second limiting part 104.

[0054] It should be further noted that in this embodiment, the first groove 105 is located at the center of the end face of the second limiting part 104. In other embodiments, the first groove 105 may also be located at other positions on the end face of the second limiting part 104, as long as the first groove 105 does not exceed the end face of the second limiting part 104.

[0055] It should also be noted that the shape of the first groove 105 can be circular, rectangular, polygonal, etc., and can be designed according to the actual situation. It is only necessary to ensure that the first groove 105 is evenly distributed on the second limiting part 104.

[0056] Based on the above embodiment, the groove includes a plurality of second grooves 106, which are arc-shaped pieces and evenly distributed on the inner wall of the through hole 102. The second grooves 106 extend along the direction of the through hole 102. The clamping member 2 includes a second adjusting part 202 extending towards the second limiting part 104 to form a cooperation with the second grooves 106. Based on the first groove 105, the second grooves 106 are formed on the inner wall of the through hole 102. When the second adjusting part 202 on the clamping member 2 is inserted... After the second groove 106 is inserted, the overall stiffness of the second limiting part 104 can be changed, thereby changing the damping frequency of the second limiting part 104. The second groove 106 is an arc-shaped plate, which can ensure that the contact area between the second adjusting part 202 and the second limiting part 104 is large, thereby ensuring that the second adjusting part 202 can achieve a better stiffness change. The second groove 106 is evenly distributed on the inner wall of the through hole 102, ensuring that after the second adjusting part 202 is inserted into the second groove 106, the second limiting part 104 can achieve a relatively uniform stiffness change.

[0057] It should be noted that the depth of the second groove 106 is not greater than the height of the second limiting part 104, so as to ensure that the second adjusting part 202 will not pass through the second limiting part 104.

[0058] It should also be noted that by simultaneously opening the first groove 105 and the second groove 106, the damping frequency of the damper can be adjusted, thus enabling the adjustment of multiple damping frequencies of the damper. The damper has a large number of damping frequencies to accommodate different types of steering wheels.

[0059] like Figures 1-3 As shown, in some embodiments, the groove includes a plurality of second grooves 106, which are arc-shaped plates. The second grooves 106 are evenly distributed on the inner wall of the through hole 102 and extend along the direction of the through hole 102. The clamping member 2 includes a second adjustment part 202 extending towards the second limiting part 104 to form a cooperation with the second groove 106. The damping frequency of the damper of the second limiting part 104 is adjusted by opening only the second groove 106. The opening position, shape, and depth of the second groove 106 are the same as those of the second groove 106 when the first groove 105 and the second groove 106 are opened simultaneously, and will not be further described here.

[0060] like Figures 1-4As shown, in some embodiments, the connecting portion 302 has a notch that divides the cylindrical connecting portion 302 into two sets of arc-shaped elastic sheets. The two sets of arc-shaped elastic sheets extend outward to form two sets of pressing portions 303. The pressing portions 303 press and fix the annular clamping member 2 onto the second limiting portion 104. By opening a notch in the connecting portion 302, the connecting portion 302 is divided into two sets of arc-shaped elastic sheets, which facilitates the pressing portions 303 to move through the through hole 102 to the second limiting portion 104. The ends of both sets of arc-shaped elastic sheets extend outward to form pressing portions 303. After the pressing portions 303 pass through the through hole 102, they press and fix the clamping member 2 onto the second limiting portion 104, thereby realizing the connection between the clamping member 2, the elastic body 1, and the support member 3. The clamping member 2 is annular, ensuring that the connecting portion 302 can press and fix the clamping member 2 at any angle through the pressing portions 303.

[0061] like Figures 1-3 As shown, in some embodiments, the elastic body 1 and the clamping component 2 are made of materials with different stiffnesses. The stiffness of the clamping component 2 is greater than that of the elastic body 1, so that the second damping frequency is greater than the first damping frequency. The material stiffness of the clamping component 2 is greater than that of the material stiffness of the elastic body 1, ensuring that after the adjustment part of the clamping component 2 is embedded in the groove on the elastic body 1, the overall stiffness of the elastic body 1 will increase, thereby increasing the damping frequency of the elastic body 1. By selecting clamping components 2 with different numbers of adjustment parts, different damping frequencies of the elastic body 1 can be achieved.

[0062] It should be noted that in this embodiment, the elastomer 1 is made of ethylene propylene rubber or silicone; the regulator is made of nylon or polyoxymethylene resin; and the support 3 is made of polyoxymethylene resin or thermoplastic elastomer 1 material.

[0063] It should also be noted that in other embodiments, the material stiffness of the clamping component 2 may be less than that of the material stiffness of the elastomer 1, and the second damping frequency may be less than the first damping frequency.

[0064] Based on the same inventive concept, this specification also provides a damper kit, including an elastic body 1, a support member 3, and several clamping members 2. The elastic body 1 has four slots, and the several clamping members 2 are respectively provided with one or two sets of adjustment parts. One set of adjustment parts consists of two adjustment parts distributed diagonally. The elastic body 1, support member 3, and clamping members 2 are any of the elastic body 1, support member 3, and clamping members 2 described above.

[0065] like Figures 1-5 and Figures 8-10As shown, in practice, by opening four first slots 105 and four second slots 106 on the elastic body 1, the first adjustment part 201 of the clamping member 2 cooperates with the first slots 105, and the second adjustment part 202 of the clamping member 2 cooperates with the second slots 106. By selecting clamping members 2 with one or two sets of first adjustment parts 201 and / or second adjustment parts 202, the elastic body 1 can have different stiffnesses, thereby changing the damping frequency of the elastic body 1.

[0066] It should be noted that the clamping components 2 may include the following six types:

[0067] Type 1, clamping component 2 without adjustment section;

[0068] Type 2, only one set of clamping components 2 of the second adjustment section 202 is provided, such as Figure 8 As shown, the frequency of the type 2 damper was measured to be 33.34 Hz ​​by sinusoidal frequency sweep.

[0069] Type 3, with only two sets of clamping components 2 of the second adjustment section 202;

[0070] Type 4, with only two sets of clamping components 2 of the first adjustment section 201, such as Figure 9 As shown, the frequency of the type 4 damper was measured to be 41.32 Hz by sinusoidal frequency sweep.

[0071] Type 5, which simultaneously provides two sets of first adjustment parts 201 and one set of second adjustment parts 202 clamping components 2;

[0072] Type 6, simultaneously providing two sets of first adjustment parts 201 and two sets of second adjustment parts 202 clamping components 2, such as Figure 10 As shown, the frequency of the type 6 damper was measured to be 50.79 Hz by sinusoidal frequency sweep.

[0073] like Figure 5 As the number of the first adjustment unit 201 and / or the second adjustment unit 202 increases, the adjustment frequency of the damper gradually increases, that is, the adjustment frequency of the regulators corresponding to the above six clamping components gradually increases. Figures 8-10 The test results show that the steering wheel with different types of clamping components 2 was tested using a sinusoidal frequency sweep vibration test method. The overall natural frequency of the steering wheel was obtained, which confirms the frequency adjustment effect of the clamping component on the damper. Therefore, different types of clamping components 2 can be selected for installation according to the actual vehicle requirements, thereby avoiding resonance and reducing the vibration amplitude of the steering wheel when the car is driving on bumpy roads.

[0074] It should also be noted that the clamping components 2 may also include the following types:

[0075] Only one set of clamping components 2 of the first adjustment section 201 is provided;

[0076] Simultaneously, a set of first adjustment parts 201 and a set of second adjustment parts 202 are provided to clamp the component 2;

[0077] Simultaneously, a first adjustment part 201 and two second adjustment parts 202 are provided to clamp the component 2.

[0078] like Figures 1-7 As shown, based on the same inventive concept, this specification also provides a steering wheel, including a mounting part 5, a pan head screw 4, a spring 6, a support 7, and a damper as described in any of the above. The damper is mounted on the mounting part 5. The support 7 has a threaded groove that mates with the pan head screw 4. The screw portion of the pan head screw 4 passes through the through hole 102 and the spring 6 and mates with the threaded groove. The spring 6 is installed between the support 7 and the support member 3. The spring 6 always pushes the support member 3 away from the support 7 until the clamping member 2 abuts against the pan head portion of the pan head screw 4 to ensure the pan head screw 4... The head portion presses the clamping component 2 onto the elastic body 1. The first limiting portion 103 and the second limiting portion 104 of the elastic body 1 are located on both sides of the mounting portion 5, so that the damper is mounted on the mounting portion 5. A threaded groove that mates with the pan head screw 4 is opened on the support 7. The shank of the pan head screw 4 passes through the through hole 102 and the spring 6 on the elastic body 1 in sequence and then mates with the threaded groove. The first end of the spring 6 abuts against the support 7, and the second end of the spring 6 abuts against the support member 3. The spring 6 always pushes the support member 3 to move away from the support 7, ensuring that the clamping component 2 and the pan head portion of the pan head screw 4 are in abutting state, thereby realizing the installation between the damper, the spring 6, the pin and the support 7.

[0079] It should be noted that by adding a clamping component 2 between the elastomer 1 and the pan head screw 4, not only can the stiffness be adjusted and the resonant frequency changed, but the friction between the elastomer 1 and the pan head screw 4 can also be isolated, reducing the wear of the elastomer 1. At the same time, the impact load between the pan head screw 4 and the mounting part 5 on bumpy roads can also be reduced, thus reducing noise.

[0080] The specific installation steps for the damper are as follows:

[0081] The elastomer 1 is mounted on the mounting part 5, and the first limiting part 103 and the second limiting part 104 of the elastomer 1 are respectively located on both sides of the mounting part 5.

[0082] The support member 3 is installed on the elastic body 1, the support portion 301 of the support member 3 contacts the first limiting portion 103, and the connecting portion 302 of the support member 3 passes through the through hole 102.

[0083] The clamping component 2 is installed on the second limiting part 104 of the elastic body 1. The first adjusting part 201 and the second adjusting part 202 on the clamping component 2 correspond to the first groove 105 and the second groove 106 on the elastic body 1, respectively. The clamping component 2 is pressed and fixed on the elastic body 1 by the pressing part 303 of the support member 3 to form a damper.

[0084] The damper is mounted on the support 7 using pan head screws 4 and spring 6.

[0085] like Figure 7 As shown, in some embodiments, the mounting part 5 includes a horn plate 501. The horn plate 501 has a first through groove for the elastic body 1 to pass through. The first limiting part 103 is located on the first side of the horn plate 501, and the second limiting part 104 is located on the second side of the horn plate 501. When the mounting part 5 is a horn plate 501, the elastic body 1 is installed in the first through groove by opening the first through groove on the horn plate 501. The first limiting part 103 of the elastic body 1 passes through the first through groove and is located below the horn plate 501, and the second limiting part 104 is located above the horn plate 501. The installation of the elastic body 1 and the horn plate 501 is achieved through the interaction between the first limiting part 103 and the second limiting part 104 and the horn plate 501.

[0086] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. In particular, the method embodiments described later are relatively simple in description since they correspond to the system, and relevant parts can be referred to the descriptions in the system embodiments.

[0087] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
